Abstract
A process for production of chlorine dioxide and chlorine by reacting sodium chlorate with chloride ions and sulfuric acid where the chlorine ions partly are obtained from hydrochloric acid is described. In the process chlorine obtained as a by-product is reacted with sulfur dioxide in a reactor equipped with a condenser. The heat of reaction is removed by keeping the reactor at or above the boiling point of the reaction medium and the vapors are condensed in the condenser and brought back to the reactor. The obtained mixed acid comprising sulfuric acid and hydrochloric acid is returned to the chlorine dioxide reactor.
